[MPROVEMENT IN HAND-STAMPS.

Specification forming part of Letters Patent No. 125,788, dated April 16, 1872.

To all whom it may concern:

Be it known that I, EDMUND D. CHAMBER- LAIN, of the city of New York, have invented a new and Improved Check-Protector, of which the following is a clear, full, and exact description, reference bein g had to the accompanying drawing making a part of this specification, in which- Figure I is a top view with the `plunger broken away. Fig. II is a side view, showing the plunger in position over the sliding bars but withthe connecting portion broken away. Fig. III is a sectional view through the line w Fig. IV is a sliding bar, detached from the protector.

A is the bed-plate of the machine, which bed-plate should be substantially constructed to resist the jar of the plunger. B is a box or casing secured in position on the bed-plate, as shown in position in Fig. I. In this casing slide the bars n u,having on them the desired iigures or letters',' as shown in Fig. IV. These bars are also provided with notches a n into which iit the spring-pins p to hold the bars securely in position while the protector is being used. Across the fa'ce of the casing B is an opening, a' a, (see Fig. I,) at which the gures or letters on the sliding bars are exposed to the plunger C, and over which the check or other instrument of writing to be protected is placed 5 then, by suddenly depressing the plunger, an impression, corresponding to the gures or letters exposed at the opening a a, will be made upon the check and at the pointvdesired. Supposing the check to be drawn for ve thousand dollars, the sliding bars n u are drawn until the same figures are exposed at the opening a a. The c hcck is then placed on the protector in such a way that the ligures on the check will be brought immediately above the opening a a. The plunger C is then brought down and the figures denoting the amount for which the check is drawn is stamped as well as written upon its face, and defies alteration. t i

The plunger C can be secured to the springbars d, or arranged in any other convenient manner for operating it upon the sliding bars.

Instead of. the sliding bars with letters or figures out, molded, or stamped thereon, a series of letters or figures may be joined together so as to slide or move over a bed-plate and accomplish the purpose sought.

By reference to Fig. IVit will be seen that for convenience sake I make a complete dupli-V cation ot' igures on the sliding bar. By this arrangement the bars are readily adjusted for use, as the eye easily catches'the figures, which are drawn outside of the casin g B, and by which the operator determines the proper position of the slidin gbars under the plunger. (See Fig. I.) Having thus described my invention, what I claim as my invention, and desire to secure by Letters Patent, is-

A check-protector, consisting of the bedplate A, casing B, sliding bars n n, constructed as described, and plunger C, all arranged and operated substantially as and for the purpose set forth. EDMUN D D. CHAMBERLAIN.
